If you hammered the 1-2 shift and didn't turn off the traction control, what you likely heard were the brakes slamming on. A loud "clunk" just after hammering into second. This is the ECU trying to shut down the wheel spin and keep it pointing straight. Sort of just as you feel the power hit the pavement, it almost sounds like a swaybar clunk when a link is bad.
That also makes a huge dent in power-feel for gear 1 and 2, as it will toast the front tires through both... It feels like a totally different car with it off to me. And with stabilitrack in sport or off, it is a super neutral handler. Put it right on the edge on a long sweeper and it will 4 wheel drift, if you work the throttle on and off it will tail out a little. It's one of the best handling little 4 doors I have ever driven. It feels smaller than it is, it feels like a MINI Cooper S does.
